New cmsDriver Step syntax ( > CMSSW_7_5_0_pre2 )

default steps

• GEN : generation of particles
• SIM : detector simulation
• RECOBEFMIX : RECOnstruction BEFore MIXing : the part of reconstruction executed before PU mixing and digitization. This consists mainly of iterative tracking.
• DIGI : PU mixing and digitization
• L1 : emulation of the L1 trigger
• L1Reco : reconstruction of L1 trigger objects
• RECO : all reconstruction except the part done in RECOBEFMIX
• EI : a high-level reconstruction step used in validation (only ran for validation purposes)
• HLT:@relval25ns : High Level Trigger
• VALIDATION : creation of histograms for validation (only ran for validation purposes)

steps to use when overlaying events with pre-generated PU events

• the default steps are used

steps to use when overlaying events with pre-mixed PU events

• DIGIPREMIX_S2: ??
• DATAMIX: overlays events with pre-mixed PU events
